Open with just one finger! I found a goods called "One Push! Wet Sheet Lid" at Daiso, a 100-yen shop.
A lid that can be attached to packages such as wet wipes and disinfectant sheets. As the name suggests, it can be used with one push, and when you press the button labeled "PUSH" with your finger, it pops open.
Since the adhesive strength of the adhesive surface is durable, it can be replaced with a new package when the wet sheet inside is used up. You can also wash it with water. The wet sheet that can be attached must have an outlet of W60 x H30 mm or less and be free of dirt and unevenness. The "PUSH" button is a little hard, so you need to push it in with your finger. When used by small children, it may be safe to have the adults around them support you.
The price is 108 yen each (tax included). How about using it for summer trips and the outdoors?
